The origin of the UTMB World Series
Since its start in Chamonix in 2003, and building on that success ever since, the UTMB Mont-Blanc has grown to be the world's leading trail event and is the inspiration behind the creation of the UTMB World Series circuit, based on the same founding principles: surpassing one's limits, fair play, respect for people and the environment and solidarity.
Starting in 2023, the UTMB Mont-Blanc will host the prestigious UTMB World Series Finals each year, crowning champions on its three iconic races: UTMB, CCC and OCC.
